 Based upon parallax measurements, η Crucis is located 64 light-years from the Sun.The system made its closest approach about 1.6 million years ago when it achieved perihelion at a distance of roughly 26 light years.This is an F-type main sequence star with a stellar classification of F2 V. It has 130% of the Sun's radius and shines with 7 times the luminosity of the Sun from an outer atmosphere with an effective temperature of 6,964 K. Observations of the system using the Spitzer Space Telescope show a statistically significant infrared excess of emission at a wavelength of 70μm.
